'almost.all' '(∀)' refers concisely to
the differences in definition at
the center of our discussion.

There is no "last" natural numbers, as BY DEFINITION, every natural number has a successor that is bigger than it.>Right.
I think that you (WM) would deny that.
You would say, instead,

The notation a͚ or S͚ for aₗᵢₘ or Sₗᵢₘ
is tempting, but
it gives the unfortunate impression that
a͚ and S͚ are the infinitieth entries of
their respective infinite.sequences.
They aren't infinitieth entries.
They are defined differently.

Wrong.
Almost all finite.cardinals are larger than
finite.cardinal n+1
{n+2} isn't large enough to change that.
Almost all finite.cardinals are larger than
finite cardinal n+2.
No, you just don't understand what you are talking about.>No. They are invariable numbers like ω and ω+1. The alephs differ only because they count potentially infinite sets which always can be bijected as far as is desired.>#E(n+2) isn't any of the finite.cardinals in ℕ>
It is an infinite number but
even infinite numbers differ like |ℕ| =/= |ℕ| + 1.
Infiniteᵂᴹ numbers which differ like |ℕ| ≠ |ℕ| + 1.
are finiteⁿᵒᵗᐧᵂᴹ numbers.
Nope. I guess you don't know what a limit actually is.>A limit is a number or set such that nothing fits between it and all numbers or sets of the sequence.
The concept of 'limit' is a cornerstone of
calculus and analysis and topology.
Dark cardinals don't exist in the finite realm.>For each finite cardinal that can be defined this is true. Dark cardinals never have been considered.
That cornerstone rests upon 'almost.all'.
Each finite.cardinal has infinitely.more
finite.cardinals after it than before it.
Sure it does. It might be needed to make it work in your broken logic system, but that is because your logic is broken.If one re.defines things away from that,Without dark cardinals set theory does not make sense.
it is only an odd coincidence if, after that,
any part of calculus or analysis or topology
continues to make sense.

∀n ∈ ℕ: |ℕ \ {1, 2, 3, ..., n}| = ℵo
and
|ℕ \ {1, 2, 3, ...}| = 0
would contradict each other because more than all n are not in {1, 2, 3, ...}.
